Accuracy of four sarcopenia screening methods in patients with chronic stroke in Thailand: a cross-sectional study

The accuracy and diagnostic properties of calf circumference, SARC-CalF, and Ishii's score chart were comparable (mean AUC of 0.77, 0.75, and 0.78, respectively). SARC-F showed the lowest accuracy (mean AUC = 0.58). The recommended screening tools are calf circumference, SARC-CalF, and Ishii's score chart. It is not recommended to rely solely on SARC-F for screening sarcopenia after stroke. We proposed potential new cutoff points for each screening instrument, including SARC-F, SARC-CalF, calf circumference in women, and Ishii's score chart for both men and women.
